Objective To explore the expression of annexin A10 (ANXA10) in human hepatocellular carcinoma (HCC),and analyze its correlation with matrix metalloproteinases-9 (MMP-9) and vascular endothelial growth factor (VEGF),thus to provide the basis for clinical diagnosis and assessment of HCC.Methods 88 HCC patients were selected,and they were all performed surgical treatment,HCC stage Ⅰ in 11 cases,stage Ⅱ 25 cases,stage Ⅲ 31 cases,stage ⅣV 21 cases.The expressions of ANXA10,MMP-9,VEGF of HCC cancer tissues,adjacent liver tissues and normal liver tissues were tested by immunohistochemical method.The correlation of ANXA10 with VEGF and MMP-9 was analyzed.Results The absorbance value of ANXA10 expression in the HCC cancer tissue was (0.074 ± 0.012),which was lower than that in the adjacent liver tissues [(0.091 ± 0.013)] and normal liver tissues[(0.131 ±0.025)],and ANXA10 expression of the adjacent liver tissue was lower than that of the normal liver tissues,the differences were statistically significant (t =8.96,9.44,8.71,all P ＜ 0.05).The absorbance values of MMP-9 and VEGF expression in the HCC cancer tissue were (0.147 ± 0.017) and (0.127 ± 0.028),respectively,which were higher than those in the adjacent liver tissues [(0.096 ± 0.012),(0.091 ± 0.015)] and normal liver tissues [(0.075 ± 0.014),(0.077 ± 0.019)].The absorbance values of MMP-9 and VEGF of the adjacent liver tissues were higher than those of the normal liver tissues,the differences were statistically significant (t =8.05,9.30,8.11;8.28,9.51,8.02,all P ＜ 0.05).The absorbance value of ANXA 10 expression in the HCC stage Ⅲ + Ⅳ cancer tissue was (0.056 ± 0.010),which was lower than that in the stage Ⅰ + Ⅱ cancer tissue [(0.082 ±0.016)],the difference was statistically significant (t =8.90,P ＜ 0.05).The absorbance values of MMP-9 and VEGF expression in the stage Ⅲ + Ⅳ cancer tissue were (0.157 ± 0.022) and (0.169 ± 0.033),respectively,which were higher than those in the stage Ⅰ + Ⅱ cancer tissue [(0.114 ±0.015),(0.091 ±0.021)],the differences were statistically significant (t =9.13,9.72,all P ＜ 0.05).ANXA10 was correlated with MMP-9 and VEGF (r =0.324,0.295,all P ＜ 0.05).Conclusion ANXA10 presents lower expression in HCC cell,and the expression decreased with the increase of staging.It is negatively related with the MMP-9 and VEGF.ANXA10 expression missing or inactivation of malignant change may be one of the most important features in HCC.

Background and purpose: The diagnosis of thyroid papillary carcinoma sometimes is difficult, metastasis of lymph node is the major reason of local relapse and influence prognosis.This study explores the immunohistochemical expression and their diagnostic value of CK19,HBME-1,galectin3,p27 and cyclinD1 in thyroid papillary carcinoma and the relations between p27,cyclinD1 and lymph node metastasis of papillary carcinoma.Methods: Immunohistochemical staining was used on 50 specimens of benign lesions (40 speciments of nodular goiters and 10 cases of follicular adenomas) and 50 specimens of papillary carcinomas (40 specimens of classic variants and 10 specimens of follicular variants) operated in our hospital from January of 2005 to December of 2008. Results: CK19,HBME-1 and galectin3 were expressed in cytoplasm or on the membrane, but p27 and cyclinD1 were expressed on the nucleus. The expressions of CK19,HBME-1 and galectin3 in thyroid papillary carcinoma were middle to strong positive, the positive ratios were 100%,96% and 100%, respectively;their expressions in benign lesions were negative or low positive, the positive ratios were 10%,10% and 6%, respectively;there were statistical differences between them (P<0.01). The expression of p27 in thyroid papillary carcinoma was low positive or negative, the positive ratio was 14%, but the expression of p27 in benign lesions was middle to strong positive, the ratio was 84%, there was also significant difference between them(P<0.01). The expression of CyclinD1 were similar in benign and malignant lesions of thyroid, the positive ratios were 68% and 78%, respectively, there was no statistical difference between them(P>0.05). There were significant differences(P<0.01) between the benign lesions and the papillary carcinomas in terms of the combination of CK19,HBME-1 and galectin3 expression and there were no significant differences(P>0.05) in the group of the former with underexpression of p27 between the two groups. The differences were not statistically significant (P>0.05) between the underexpression of p27 with the expression of cyclinD1 (the positive ratios in metastasis group and no metastasis group are 72.7% and 71.4%) in the lymph node metastasis. Conclusion: The combined immunohistochemical stainings of CK19,HBME-1 and galectin3 are useful on the diagnosis and differential diagnosis of thyroid papillary carcinoma, there is no predicted value of the underexpression of p27 with the expression of cyclinD1 for lymph node matastasis of thyroid papillary carcinoma.

Objective To study the application value of radiotherapy optimization after modified radical mastectomy.Methods From January 2012 to January 2015,one hundred and twelve patients treated with modified radical mastectomy in Taizhou Cancer Hospital were enrolled and divided randomly into group A,B and C.40 patients in group A received modulated radiation therapy(MRT) with 2.0Gy/f,25 times,DT50Gy for 33-35d;35 cases in group B received concurrent chemoradiotherapy with MRT and 37 cases in group C received concurrent chemoradiotherapy with large segmentation scheme of 2.66Gy/f,16 times,DT42.56Gy for 22-24d.The recurrence rate,survival rate and the incidence of acute and chronic radiation injury of the 3 groups were compared.The parameters of V5,V10,V20 and V30 of ipsilateral lung was recorded by dose volume histogram(DVH).Results The total recurrence rate in group C was significantly lower than that of the other two groups (16.2％(6/37) vs.28.6％(10/35) vs.42.5％(17/40),x2 =6.409,P=0.041),while the total survival rate was significantly higher than that of the other two groups (89.2％ (33/37) vs.77.1％ (27/35) vs.65.0％ (26/40),x2 =6.313,P =0.043),and there was no significant difference in the local recurrence and distant metastasis rate in the 3 groups (P＞0.05).The incidence of total radiation injury in group C was lower than that of the other two groups (21.6％ (8/37) vs.42.9％ (15/35) vs.50％ (20/40),x2 =6.973,P =0.031),and there was no significant difference in the incidence of acute and chronic injury and the grade of injury in the 3 groups (P＞0.05).The values of VS,V10,V20 and V30 increased gradually in the 3 groups.The V5 and V10 in group C were significantly higher than those of the other two groups ((32.9 ± 7.4) ％ vs.(17.5 ± 5.9) ％ vs.(16.8 ± 6.4) ％,F =18.625,P=0.000,(42.4±7.3)％ vs.(39.3±5.8)％ vs.(35.5±6.0)％,F=15.624,P=0.000),and there was no significant difference in V20 and V30 among the three groups (P＞ 0.05).Conclusion The combination of concurrent chemoradiotherapy and breast cancer after modified radical mastectomy is of great value in improving prognosis and reducing radiation damage.
